Job State

An arduino module interfaced with gas sensors with gsm module that sends sensor data to a cloud repository and receives instructions based on the readings, preferably using JavaScript and server-client capabilities.

Need wiring diagram for junction box that will be placing 6 inputs and 5 outputs along with 480V and 120V feeds for pumps/relays. P&ID as well as components that will be placed in the box are available.

From the provided datasheet write a 1/8 generic driver for a ROHM BU97950AFUV to setup for either 3.3v or 5v supply.A class library where a graphic is in memory array and can be displayed in a similar manor used to drive common Nokia 84x84 displays

Hello. I just need to change an Arduino code. I have already one and it works good but it need to be improved. I will change it because my 2DOF Motion Simulator works right now with pot and I will change it to rotary encoder including opto sensors.
And still one small issue. But for someone who knows C++ it should be not that difficult. You also should

Require an app to control the speed of a hydraulic motor via a PWM valve.
The app will control a machine and the faster the machine is driven forward the faster the hydraulic motor needs to turn.
We will use GPS speed and an actual speed pulse from the machine to determine the output signal to the PWM valve
We need 12V controller with Bluetooth connection

...button one on the transmitter is pressed , signal the receiver to tell the main board to spin the motor clock-wise until sensor two is pressed.
2. When button two on the transmitter is pressed , signal the receiver to tell the main board to spin the motor anti clock-wise until sensor one is pressed.
I will need the code and the boards made and delivered

We work for a mining organisation and require solutions to control PLCs wirelessly using ne...lights and other simple equipment.
The challenge here is the location which is a remote mining area, so no optic fibre cables are present, we have LTE connectivity only and wiring is not an option as the terrains of mining area keeps on changing constantly .

I need a simple midi controller based on a US Digital S1-512-B rotary encoder.
The controller n...higher the number.
It needs to be most sensitive in the slow rotation range.
Because of the low resistance of the encoder it can turn very fast.
This could be done with an arduino but doesn't have to. The encoder needs +5v.
I don't need any type of case.

...case/bag, belt clip (accessories to protect, to help organize, to avoid loosing parts, etc)
4 - Can I use the power drill to drill rubber or plastic?
5 - How to tell if the drill motor is being forced/stressed
Thanks!...

I'm looking for this to be quite small and compact

...secondary of the transformer. Historically this is done manually until motorized controls were introduced. The transformer taps are connected using the variable arm driven by a steppermotor. The power and voltage levels do not have limitation for these regulators.
3) There are 2 types of voltage controls, step control, and continuous control.
a. The step

...air temperature, humidity, atmospheric pressure, CO2 (dioxyde), VOD, visible light intensity (even UV if possible).
Sensors must be SMD type and must communicate to the MCU(arduino like/ESP8266/raspberry) via I2C so that an user can chain more than a such PCB on the same MCU pins. Components can be cheap but reliable.
Connector on the PCB has to be JST

I want to have an android based app where I can send mp3 files via wifi from my phone to an arduino based gadget with an esp32 module and make the esp32 play it. I don't want to use a separate mp3 card, everything must be done within the esp32. The MP3 files must be in the phone and sent to ESP32. If you already have the solution please bid.

A small project for Arduino platform including control of steppermotor, Oled display, rotary encoder, I/0 triggers and a simple menu system.
Short, a smal system for feeding wire with some precise control.
External trigger will start a cycle to feed a wire based on some settings i the local program.
16 different programs to choose between from

I need a pattern design drawn up for a wooden motor boat. I have an instruction manual typed up already for how to build this motor boat but I need patterns that can be cut out and traced onto wood. The pictures below show what I need as far as sizing goes and I’ve attached the instruction manual for your reference. I need the base of the boat, the

...different application. Only StepperMotor (currently used in Eora 3D Scanner) is going to be used in my NEW Project. No 3D Scanning Features will be included in my project. No laser. No Camera.
Reference: Eora 3D Scanner Hardware is using very simple solution - Bluetooth communication with single Bluetooth Chip and StepperMotor Controller from Texas Instruments

At startup move runners, stacker (not shown) and nail guns to a home position using limit switches then enter a pallet size (width and length) onto a screen to move step motors on actuators, moving the two outside runners, stacker and nail guns in or out to the size of the pallet.

...IN LOS ANGELES) I purchased a small bottle labeling machine from China and a part of the machine is not working properly - specifically an optical sensor is not triggering a motor that it is supposed to. I have no experience with this kind of thing and I need somebody to troubleshoot this machine for me.
The task seems to be a simple one, but if it turns
